Doing the Adrift Expedition Redux (even though I've already done Adrift, I just like doing Expedition), and ran into this at Rendezvous 4, a derelict freighter pretty much crashing into the planet. It apparently tilts gravity, and severely hampers your jump jets. TIL I guess.
I also did the freighter task for free, saving the scanner, so thank to whoever parked a derelict freighter right on top of the rendezvous. Saw lots of other people going into the freighter at the same time, so I think it helped out.
Quite some time ago I had a bug with two planets overlapping.
It messes the gravity alright, for a while it was twitching between the two and, as often with that kind of glitch, I ended clipping through the ground into the void.
I've seen screenshots of this happening, but I haven't seen it first hand. I think that colliding planets are persistent? I.e. you can glyph to those planets later and they would still be colliding the same way? I should check it out sometime.
The gravity at this freighter was messed up as well, but the main effect is "less jetpack" (as opposed to more cowbell). It happened earlier at an ancient ruin, and it was worse, the ground was subjectively completely vertical, jetpack was useless, and there was a radioactive storm. I managed to dig out after fetching up against a hill, but no screenshot from that one.
As I understand it, the colliding planets let you jetpack fine, it just messes with where down is, allowing very long flight times like those gravity storms.
Yeah, I think I could still jetpack, but it was messy. It's been a while, and I didn't think of getting the glyphs.
